Abstract
In current business practice, an integrated approach to business and IT is indispensable. As a real-life example, take the Dutch government, who are currently undertaking a massive redesign of the entire chain of organisations involved in the social security system. Within this context, the collection of employees’ social security premiums is transferred from the central social security organisation to the tax administration. This sounds logical, since collecting taxes is superficially very similar to collecting social security premiums. However, this seemingly simple change entails a major redesign of organisational structures, business processes, IT applications, and technical infrastructure. Enormous flows of data need to be redirected within and among the different organisations: more than 600,000 payroll tax returns are filed each month, a large proportion of which arrive within a peak period of a couple of days.
